Abstract : Specific heat and speed of sound data were computed for imperfect nitrogen. The thermodynamic data included the effects of two-body intermolecular forces, and the results were obtained by numerical interpolation and differentiation of the recent data of Hilsenrath and Klein (AD-432 210). Results are given for the ranges T = 2000(100)15,000 K and log RHO = -6.8(0.2)2.2. Comparisons with previous perfect gas calculations showed small effects on the specific heat data at all pressures considered; however, at pressures near 1000 atm, the effects were larger on the speed of sound data. (For T = 100 to 2200 K see AD-601 205). (Author)
